If Lee decides on Gettysburg-style "Yaah, let's go get 'em" attacks he doesn't need 1,000,000:1 odds to lose horribly. Given that the actual numbers were 38,000 against 75,000, McClellan would have an easy victory by letting Lee batter his army to death.
See, "actual numbers" that exclude unengaged formations, officers, artillery, and other odds and sods....
